The Poop Scoop: Using Feces to Track Ebola Infection and Survival Wild Apes

Posted 29 September 2014 by Anne-Marie Hodge

Prologue: In case you have been completely isolated from the news in recent months, here’s a recap: West Africa (principally Sierra Leone, Liberia, Senegal, Guinea and Nigeria) is experiencing an unprecedentedly wide outbreak of Ebola, and the epidemic continues to snowball with each passing day. Medical treatments in most developed countries could likely contain or limit such an outbreak (we hope), but under-resourced West and Central African countries have not been able to curb the spread of the virus.

These "alien" invasive plants and animals can (and often do) wreak havoc on native species, because local organisms often lack the adaptations to deal with a novel predator and/or competitor to which they've never before been exposed. Entire ecosystems have been disrupted... Read more

Prions Survive Crow Guts

Posted 15 December 2012 by Anne-Marie Hodge

Mad cow disease, kuru, chronic wasting disease—all of these ghastly illnesses are caused by prions--misfolded proteins in the brain, which are more technically known as transmissible spongiform encephalopathies (TSEs). Once a prion infection sets in, the results are gruesome. Loss of muscle control, hallucinations, general neurological meltdown . . . the symptoms of prion disorders can lead to truly tragic and painful deaths, all ultimately due to a few key misshapen proteins (see this neat interactive animation for a refresher...
